DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention include systems and methods of attachingtoys or other items to child care equipment, and include pieces of childcare equipment having features for attaching toys or other items.

In some embodiments, the piece of child care equipment is configured toinclude a track, such as a rod, and a sliding member that moves alongthe track. The sliding member is configured so that one or more toys orother items can be easily and releasably attached to it. Toys or otherattached items can be interchanged and moved to different locations asdesired. For example, the track may be suspended above a baby in a playgym, and toys hanging from the track may be moved to be within thebaby's reach. The track may also be part of another kind of equipment,such as a pad or pillow, and attached toys or other items can be movedto a location where the child is lying. Other kinds of attachments mayalso be provided. The track may be completely embedded within the pieceof equipment, such as within a fabric sleeve, with the clip sliding overa fabric sleeve. Alternatively, the track may be coupled to theequipment such that the track remains exposed. In this way, the clipslides directly over the track.

For example, FIG. 1A shows an infant play gym 100 in accordance withembodiments of the invention. Play gym 100 comprises a base pad 101, anda canopy 102. In one mode of use, play gym 100 is placed on a floor.Base pad 101 includes a padded center portion 101 a and a paddedperipheral portion 101 b that forms an outer boundary for holding thebaby. A seam is formed between portions 101 a and 101 b where the fabricfrom each of the portions is joined together. One convenient way toconstruct base pad 101 is by placing a batting on the fabric, thensewing the fabric together to form the various seams. The stitchingbetween center portion 101 a and peripheral portion 101 b serves tolimit the amount of shifting of the fill material. An infant is placedon base pad 101, and may interact with various toys or other items suchas item 103 suspended from canopy 102 or attached to base pad 101. Playgym 100 thus provides a safe, comfortable, and convenient place for thebaby to spend time, and also provides stimulation for the baby'sentertainment and development. Play gym 100 may be especially useful forthe care of infants who have not yet begun to crawl. Having itemsattached to play gym 100 keeps the baby's toys in a contained area andwithin the baby's reach.

Base pad 101 may be, for example, made of a soft cloth or fabric, andmay be filled with padding such as foam or fiberfill padding or batting.Base pad 101 is preferably of a size suitable for holding a baby. Forexample, base pad 101 may be about 30 to 36 inches across, but otherlarger or smaller sizes may be used. Base pad 101 may be of any suitableshape, including round, oval, oblong, rectangular, or another shape.

Base pad 101 includes three attachment members 104 a-c affixed to anedge portion of base pad 101. One of skill in the art will recognizethat more attachment members may be provided. Attachment members 104 a-cmay be, for example, fabric-covered foam or fiberfill material in a ballshape, or another suitable shape. While attachment members 104 a-c arepreferably compressible, substantially rigid shapes could be used aswell, for example plastic balls. Each of attachment members 104 a-c maybe affixed to base pad 101 by sewing a portion of the covering of therespective attachment member into an edge seam of base pad 101, bysewing a tether to both the attachment member and base pad 101, or byany other suitable means.

Canopy 102 is configured to arch over base pad 101, standing on threelegs 105 a-c, forming an arched support frame. Canopy 102 may reach aheight of, for example, 12-24 inches over base pad 101, and may be usedto hang toys or other items 103 within reach of a baby placed in playgym 100. One of skill in the art will recognize that more legs and otherdimensions could be used. Canopy 102 comprises a surface sheet 106,which may be, for example, a fabric or plastic sheet, and may be of asingle thickness, or comprise multiple thicknesses of one or morematerials. Surface sheet 106 may be made of multiple pieces integratedtogether, and the pieces need not be of the same materials. Canopy 102also includes at least two semi-rigid rods 107 a and 107 b embeddedwithin canopy 102. Semi-rigid rods 107 a and 107 b may be, for example,made of a plastic, metal, or composite material, and may be round oranother shape in cross section. Semi-rigid rods 107 a and 107 b arepreferably stiff enough to remain substantially straight whenunstressed, to lightly resist bending, and to regain substantialstraightness when any bending force is removed. In one exampleembodiment, rods 107 a and 107 b are each about 28 inches long and about¼ inch in diameter, and are made of unreinforced plastic. Otherappropriate sizes may be used.

First ends of both rods 107 a and 107 b follow a first leg 105 a ofcanopy 102 to its connection with base pad 101. Preferably, rods 107 aand 107 b are embedded within edges of surface sheet 106, but otherplacements may be used. A second end of first rod 107 a also followssecond leg 105 b to its connection with base pad 101, and a second endof second rod 107 b follows third leg 105 c to its connection with basepad 101. Rods 107 a and 107 b thus support canopy 102 by virtue of theirstiffness, similar to the way a tent may be supported by tent poles.

As described in greater detail hereinafter with reference to FIG. 3A, aclip 301 is slidingly engaged with rod 107 a. Clip 301 may slideanywhere along rod 170 a to adjust the position of one or more toys thatare coupled to clip 301. This provides a convenient way for a caregiverto adjust the location of a toy relative to a child. For example, whenremoving the child from base pad 101, when changing a diaper or cleaningthe baby, the caregiver can simply slide clip 301 along rod 107 a toafford better access into the interior of the tent. To keep the childentertained, slip 301 may be slid such that the toy hangs over thearched support. Although shown attached to rod 107 a, it will beappreciated that clip 301 may be coupled to any of the rods. Moreover,multiple clips could be attached to a single rod. Also, multiple toysmay be chained together, such as toys 122 and 124 of FIG. 1A, toincrease the length of the toy and provide a different arrangement forthe toys that are suspended from base pad 101.

Base pad 101 may also include one or more tracks 130 that may be coupledanywhere along a top or side of base pad 101. Track 130 is a semi-rigidrod that may function similar to the rod 107 a in supporting one or moreclips 350 as described in greater detail hereinafter with reference toFIGS. 3C and 3D. As further illustrated in FIG. 1C, track 130 comprisesa semi-rigid rod that is coupled to base pad 101 by a fabric sleeve 132.More specifically, sleeve 132 may comprise a fabric strip that has itslengthwise ends sewn into a seam 133 in base pad 101 to form a tube.Seam 133 is the seam that is formed when connecting portions 101 a and101 b. The rod is slid through sleeve 132 and then the ends 136 and 138of sleeve 134 are sewn down and incorporated into the seam. Prior tosewing the ends into the seam, clip 350 is inserted over the fabricsleeve. In the way, clip 350 will not detach from track 130. As anotheroption, the ends of the rod may be held in pockets to secure the rod tobase pad 101. In this way, a fabric sleeve would not be needed.

One or more toys 126 may be coupled to clip 350 in a manner similar tothat described in connection with other embodiments. This allows items,such as toys to be removably coupled with base pad 101. Further, thelocation of the items can easily be adjusted by sliding them along track130 using clip 350. For example, a toy can be moved to a mid portion ofbase pad 101 to provide easy access to the toy by the child. However,when the child needs to be removed from base pad 101, clip 350 may beslid to one side to move the toy. As another example, clip 350 may beslid along track 130 to place the toy in a different location to therebyprovide a different environment within the play structure.

The fabric used to form fabric sleeve 132 should be durable because offriction caused by the slider clip when moving over the rod. The fabricshould be sufficiently durable so that the rod will not break throughthe fabric over time. Preferable fabrics include nylon fabrics. Anespecially good fabric is a denier nylon with or without a polyurethanecoating.

FIG. 1B shows canopy 102 separated from the rest of play gym 100. Canopyattachment loops 108 a-c are placed at the lower ends of legs 105 a-c.Loops 108 a-c are configured to engage the attachment members 104 a-c toattach canopy 102 to base pad 101. To make the attachment, eachattachment member is passed through its respective loop. If attachmentmembers 104 a-c are compressible, each attachment member may becompressed to pass through its corresponding loop and then allowed tore-expand. Canopy attachment loops 108 a-c may also be stretchable, sothat when the loops are unstretched, the loops are smaller than theattachment members. This arrangement may help ensure a secure attachmentof canopy 102 to base pad 101, but also allow for easy disassembly ofplay gym 100. As another option, loops 108 a-c may each comprise twostraps with ends having a hook and loop fastener material. In this way,the two straps may be wrapped about the attachment members 104 a-c andthen secured to each other about their respective ends.

Play gym 100 may comprise one or more openings for attaching items 103to play gym 100. For example, surface sheet 106 may include spaced apartholes 109, which may be reinforced by stitching around the perimeter ofthe hole or by other means. In another example, base pad 101 or canopy102 may include loops such as item attachment loops 110 shown in FIG. 1.These holes and loops may be used to attach various toys, such as, forexample, the toy in FIG. 2. However, the holes and loops can also beused with traditional toy links, also referred to as “C” clips or “C”links, to which various items may be attached.

FIG. 2 shows an example item 103 that may be attached to play gym 100.In this example, item 103 is a ball configured to attach to play gym100, but many different kinds of items may be configured to attach toplay gym 100, including such items as a toy, a block, a pyramid or othergeometric shape, a doll, a teething ring, an item comprising a mirror, atoy shaped like an animal or insect, a toy shaped like a plant orflower, or another suitable item. Preferably, items attached to play gym100 are selected to be entertaining and stimulating to an infant placedin play gym 100.

As is shown in FIG. 2, item 103 includes a main body 201 and acompressible member 202 connected to the main body 201. In this example,compressible member 202 is connected through tether 203, but otherconnection arrangements may be used. Compressible member 202 may haveany suitable shape, such as a ball shape, a block shape, a pyramid shapeor other geometric shape, a button shape, a leaf or flower shape, ananimal shape, a shape reminiscent of wings, or another shape. The shapesmay or may not incorporate sound, light or vibration features.Compressible member 202 is preferably somewhat larger in itsuncompressed state than holes 109 or item attachment loops 110. Item 103may then be attached to play gym 100 by squeezing compressible member202 through one of holes 109 or item attachment loops 110 and allowingcompressible member 202 to re-expand, providing a secure but easilyremovable connection. This attachment system has the additionaladvantage that the materials involved may be soft and pliable and all ofthe parts may be relatively large, resulting in a safe environment forthe infant.

FIG. 3a illustrates another embodiment of an attachment of an item 302to play gym 100. In this embodiment, clip 301 is slidingly engaged withrod 107 a. One or more clips such as clip 301 may be engaged with any orall rods of canopy 102. Preferably, rod 107 a is embedded in play gym100 so that it is accessible for engagement with clip 301. For example,rod 107 a may be embedded by wrapping rod 107 a in a portion of surfacesheet 106. In that configuration, rod 107 a may be thought of asresiding in a tubular pocket sewn into surface sheet 106. Not all of therod need be wrapped or embedded. Even if part of a rod is wrapped, someof the rod may be left exposed. In some embodiments, the portion ofsurface sheet 106 wrapping rod 107 a may be made of a woven nylon orother durable fabric, to provide a suitable amount of friction to clip301, and to resist wear.

FIG. 3b illustrates clip 301 in isolation. Clip 301 is generallytoroidal, but need not be perfectly toroidal. A slotted passage 303 isprovided at one side of clip 301. Slotted passage 303 is configured toslidingly engage a rod such as rod 107 a. The rod and slotted passagemay be any size, so long as passage 303 is sized so that clip 301 iseasily slid along the rod, but will maintain its position on the rodwhen left at rest. This kind of sliding fit may be facilitated by thenatural compliance of a portion of surface sheet 106 that may be wrappedaround the rod, and by the split configuration of passage 303. Clip 301is preferably substantially rigid so that it is not reasonably removablefrom the rod without sliding clip 301 past an end of the rod.

Once clip 301 is engaged with rod 107 a (or another rod) the fabric orother material wrapping rod 107 a may engage with slot 304 of passage303, and limit the rotation of clip 301 around rod 107 a. Hole 305 inclip 301 provides an opening configured for attaching items to play gym100. For example, compressible member 306 of item 302 may be passedthrough hole 305 to hang item 302 from canopy 102. Multiple clips 301may be provided on play gym 100, and one or more clips may be providedon any or all semi-rigid rods used to support a canopy. Any or all clips301 mounted on canopy 102 may be easily moved to adjust the positions ofitems such as item 302 attached to canopy 102 using clips 301.

It will be appreciated that many variations are possible in theconfigurations of the items to be attached to a piece of child careequipment such as play gym 100.

For example, referring again to FIG. 1, item 111 may comprise a mirrorsurface (which may be surrounded by suitable padding) to allow the childto see a reflection of himself or herself. Item 111 also illustratesanother variation. Item 111 includes two compressible members 112 and113, which are passed through two of item attachment loops 110, tofurther constrain the position of item 111. In another example, item 302shown in FIG. 3A has a main body in the shape of an animal. Other itemsmay have main bodies shaped like insects, plants, flowers, geometricshapes, or other objects that may entertain or stimulate the child.

In some embodiments, an item attached to a piece of child care equipmentmay generate sound. For example, a ball or other item may be filled witha material that makes a crackling sound when the ball is squeezed,encouraging the child to interact with the item. An attached item couldinclude an electronic sound generating device that plays music, animalsounds, tells a story, or generates some other kind of sound when theitem is squeezed, caused to move, or otherwise activated. In addition,an item may also incorporate a light feature or a vibration featurewhich can be activated by movement or a switch, also encouraging thechild to interact with the item.

FIGS. 3C and 3D illustrate clip 350 of FIG. 1A in greater detail. Clip350 comprises a clip body 352 that is generally toroidal in geometry.Clip body 352 has a slot 354 leading to a passage 356 through which therod will slide. Slot 354 is wide enough to prevent the fabric sleeve toslide through it. Passage 356 is sized to be just large enough so thatit can smoothly slide over the rod and fabric sleeve. If passage 356 istoo large, clip 350 will be too loose and will not easily slide, and maybe able to separate from the rod. Conversely, if it is too small, thenit will bind against the sleeve and/or rod making movement difficult.Thus, the rod should be small enough that it can be wrapped in the nylonfabric forming the sleeve and still have the clip slide, but not sosmall that the clip snaps off the rod and presents a safety hazard. Thepassage in clip 301 may be sized in a similar manner. Clip 350 alsodefines a central opening 358 where a compressible member of a toy maybe placed similar to other embodiments described herein.

Another feature of clip 350 is that slot 354 is generally perpendicularto the clip body, while with clip 301 the slot 304 is parallel to theclip body. This permits clip 350 to be generally parallel to the base101 as illustrated in FIG. 1A so that it does not stick up and interferewith the baby's play. With clip 301, the clip body is generally alignedwith the fabric on the arched support. While the clip body does extendfrom the rod, this does not interfere with the baby's play and alsoallows the toy to more easily hang from the arched support. In somecases, clips may be constructed where the slot is at different anglesrelative to the clip body, such as 15 degrees, 30 degrees, 45 degrees,60 degrees and the like, to permit the clip body to be at differentangles relative to the adjacent fabric or base layer.

Many variations are also possible in the shapes of the compressiblemembers used to attach items to the child care equipment. For example,compressible member 202 shown in FIG. 2 may be reminiscent of leaves,animal ears, or wings. Compressible member 306 shown in FIG. 3A is in asimple ball shape. Other possible shapes include a flattened ball orbutton shape, other geometric shapes, leaf and flower shapes or animalshapes.

FIG. 4 shows another example item 401 attached through a clip 301engaged with rod 107 a. In this example, item 401 includes abutton-shaped compressible member 402 engaged with clip 301. The mainbody of item 401 is generally toroidal or donut shaped having an opening403. A second item 404 is suspended from opening 403 in item 401. Inthis example, second item 404 includes a teething ring, and alsoincludes a compressible member 405 in a shape reminiscent of leaves.

Attachment systems and methods according to embodiments of the inventionmay be used with a variety of child care equipment. Play gym 100 shownin FIG. 1A is but one example. Other kinds of equipment that may embodythe invention include, without limitation, a play yard, a playpen, aswing, a baby bouncer, a shopping cart liner, a stroller, a car seat, abooster seat, a high chair, a play pad, a changing pad and a changingpad cover.

In one example, FIG. 5 shows a play yard 500 in accordance withembodiments of the invention. A play yard is a device similar to atraditional playpen, and is designed to provide a safe and constrainedspace for a child to spend time. A play yard may be placed, for example,in a corner of a room, or even outdoors when it is desired that thechild accompany a group on a picnic or other outing. Play yard 500includes features for attaching toys or other items. For example, playyard 500 includes a dome 501, which may include holes 502 for attachingitems as previously described. An edge of dome 501 may include anembedded semi-rigid rod 503 and a clip 301 slidingly engaged with rod503 for attaching items. Other portions of play yard 500 may alsoinclude openings or rods. For example, a wall or side 504 of play yard500 may include holes 502, an embedded semi-rigid rod 505, or both; orthe bottom of the play yard may include an embedded semi-rigid rod.Other examples of play yards or other play structures that may includesuch attachment systems are described in U.S. Pat. No. 7,290,303, andPublished U.S. Application No. 2007/0271703 and 2002/0042953,incorporated herein by reference.

In another example, FIG. 6 shows a swing 600 in accordance withembodiments of the invention. Example swing 600 includes an archedsupport frame 601 that includes holes 602 in a surface sheet and anembedded semi-rigid rod 603 for attaching items, for example using clip301. Swing 600 may be used, for example, to provide a place for a babyto relax, with the swinging motion providing a comfort and enjoyment forthe baby. The items suspended from arched support frame 601 provideadditional entertainment and stimulation.

FIG. 7 shows a bouncer 700 in accordance with embodiments of theinvention. A bouncer is a device used in a manner similar to a swing,but provides a bouncing motion rather than a swinging motion. Bouncer700 also includes an arched support frame 701 having holes 702 in asurface sheet and an embedded semi-rigid rod 703, for mounting itemsusing a clip 301.

FIG. 8 shows a shopping cart liner 800 in accordance with embodiments ofthe invention. Shopping cart liner 800 is configured to nest in thechild seat portion of a shopping cart to provide a clean liner overunsanitary surfaces. Liner 800 also provides protective soft surfacesfor a child to encounter, rather than the hard, cold materials of whichthe shopping cart itself is usually made. Similar liners may beconstructed for strollers, child car seats, high chairs, booster chairs,or other items in which a child may be placed, and one of skill in theart will recognize that the attachment features of shopping cart liner800 may be adapted to other kinds of liners as well. Shopping cart liner800 includes leg holes 801 and a padded shell 802. A rod 803 is embeddedin a portion of shopping cart liner 800 that a child faces when theliner is in use. As in other embodiments, rod 803 may be embedded bywrapping it in a fabric sleeve 820 or other sheet sewn into shoppingcart liner 800, or may be embedded in some other way. As illustrated inFIG. 8A, fabric sleeve 820 is sewn into a seam 822 of liner 800 suchthat it forms a tube into which rod 803 may be inserted. After insertingrod 803 into the sleeve, each end 824 of the sleeve is folded back andthen sewn onto itself as well as to the liner 800 as illustrated in FIG.8A. Alternatively, an additional piece of fabric can be sewn over theends and to the liner to insure that the ends of rod 803 will not pokethrough the sleeve. A clip 301 is slidingly engaged with rod 803, andtoys or other items 804 are attached to shopping car liner usingcompressible members passed through the hole in clip 301. Typically,slider clip 301 is inserted over rod 803 and sleeve 820 prior to sewingends 824 back on themselves to insure that clip 301 will remain attachedto rod 803. In this example, both items 804 are shaped like flowers, andboth are attached through the same opening in clip 301. Shopping cartliner 800 may also have holes 805 through which other items may beattached using the methods described above. When attached to shoppingcart liner 800, items 804 provide entertainment and stimulation to achild riding in the shopping cart, and because they are attached, arenot likely to be dropped or lost.

FIG. 10 illustrates an interior view of example shopping cart liner 800,and illustrates additional features that may be present in someembodiments. Shopping cart liner 800 includes a body 1001 configured tonest in the child seat portion of a shopping cart. Shopping cart liner800 or a similar liner could also be used in a high chair or similarchair, for example a chair of the kind often provided by restaurants forseating children at table height. The body 1001 may be made of a fabricor other similar material that is flexible and can conform to the shapeof the shopping cart while being comfortable and safe for a child seatedin shopping cart liner 800. Preferably, body 1001 is made of a washablematerial. Examples of suitable materials for body 1001 include cotton,nylon, LYCRA, denim, polyester, microfibers, synthetics, and the like.Body 1001 may be padded, for example using a batting or foam, which isalso preferably washable. In some embodiments, body 1001 may include twolayers of fabric or other flexible material with padding between thelayers. For example, a batting or other padding material could bequilted into shopping cart liner 800. A track 1005 is embedded inshopping cart liner 800 and positioned near the handle by which ashopper would push the shopping cart. (The handle is not visible in FIG.10, but is generally under track 1005 and is covered by shopping cartliner 800.) Track 1005 may be in the form of rod 803 as described above,and may be wrapped in a fabric sleeve 820, which may be sewn into a seam822 of shopping cart liner 800, or may be embedded in another way. Theends of track 1005 may be captured in the manner described above andshown in FIG. 8A.

In other embodiments, track 1005 may be made of foam, plastic, or rubberwelt material. Welt is an elongate flexible material, often circular incross section, and is available from National Bias Binding Corp. of 14058^(th) Street 2L, Brooklyn, N.Y. 11220, among other suppliers. Oneadvantage of using foam, plastic, or rubber welt to form track 1005 isthat it is machine washable. Being substantially flexible, it may alsobe configurable into complex curves and other shapes, and may permit theitem in which it is embedded to be folded, rolled, or otherwise reducedin size for packing or storage. It may be possible to sew directlyacross a track made of foam, plastic, or rubber welt, and when a trackmade of such a welt is embedded in a seam of a product, the ends of thetrack may be captured by simply turning the track through the seam andsewing across the track. This technique is explained in more detailbelow.

Openings or leg holes 801 are positioned to enable the feet of a childseated in the shopping cart to protrude through the body 1001 when thechild is seated in the lined seat portion of the shopping cart.

A clip 1004 is slidingly engaged with track 1005. Clip 1004 defines anopening for attaching an item to the shopping cart liner. Clip 1004 maybe similar, for example, to clip 301 or clip 350 shown in FIGS. 3B and3C. Any suitable item may be attached to the shopping cart liner viaclip 1004, for example, a toy, teething ring, doll, pacifier, or otheritem may be attached, by the methods described above. While only oneclip 1004 is illustrated, it is to be understood that multiple similarclips could be engaged with track 1005. One or more holes 805 may beprovided in body 1001 for attaching other items to shopping cart liner800. Holes 805 may be formed, for example, similar to buttonholes, withdense stitching around the perimeter of the hole to lend strength anddurability.

Shopping cart liner 800 may also comprise a seat belt 1002 affixed tobody 1001 or another part of shopping cart liner 800, for securing achild to shopping cart liner 800. Seat belt 1002 may include a fastener1003, which may be a buckle, snap feature, or other kind of suitablefastener. Fastener 1003 may be selected to be secure when fastened butstill relatively easily disengaged by an adult. Seat belt 1002 may befixed to shopping cart liner 800, for example by stitching. Preferably,though, seat belt 1002 is not fixed to shopping cart liner 800, butthreads through openings in the liner such that one or both ends of seatbelt 1002 can be threaded through or around bars or other features ofthe shopping cart and then the ends of seat belt 1002 connected, tosecure both shopping cart liner 800 and the child to the shopping cart.In another embodiment, shopping cart liner 800 may not include a seatbelt 1002, but may include openings positioned so that an existingsafety strap that is part of the shopping cart could be threaded throughthe liner openings and around the child.

FIG. 11 shows a rear view of shopping cart liner 800 in use. A rear flap1101 may hang down from the back of the seat portion of the shoppingcart, and may include other features for the convenience of the user.For example, one or more pockets 1102 may be sewn into rear flap 1101for holding items that a caregiver may wish to keep readily accessible,for example a baby bottle, cellular telephone, or other item. A pocketsuch as pocket 1102 may include an elastic rim 1103, for holding itemsmore securely. A specialized pocket 1104 may be specially constructed tohold a package or dispenser 1105 holding tissues or wipes, leaving thepackage or dispenser 1105 partially exposed so that tissues or wipes canbe dispensed easily. For example, pocket 1104 may be made of a set ofpartially-overlapping fabric flaps that constrain the edges of packageor dispenser 1105 while leaving the center of package or dispenserexposed. One or more flaps similar to rear flap 1101 may be provided atthe front of shopping cart liner 800, or on either or both sides of theshopping cart liner 800, and may include pockets or other features ofconvenience to the user.

FIG. 12 shows an interior view of shopping cart liner 800, used incombination with a pillow 1201. Pillow 1201 may be generally arc shaped,including two curved arms 1202 extending from a midsection 1203, todefine an open well 1204 to receive a child. Pillow 1201 may be betweenabout 12 and about 20 inches wide, and is preferably about 16 incheswide. Open well 1204 may be between about 5 and 8 inches across, and ispreferably about 6 inches across.

Pillow 1201 may be especially suitable for using shopping cart liner 800with a very small child, such as an infant. Pillow 1201 may be placed inthe lined seat portion of the shopping cart prior to or after seatingthe child. Once pillow 1201 and the child are in place, pillow 1201 mayfit around the child's waist to support the child in an upright seatedposition. Pillow 1201 may be a small version of a pillow such as isdescribed in one or more of U.S. Pat. Nos. 5,261,134, 5,661,861;6,038,720; 6,055,687; 6,685,024; 6,434,770; 6,671,908; 7,017,212;6,279,185; 6,412,128; 7,451,508; 7,127,760; 6,944,898; 7,587,773;7,472,443; and 7,404,222, previously incorporated by reference.

Features may be provided on pillow 1201, shopping cart liner 800, orboth for securing pillow 1201 to shopping cart liner 800. For example,pillow 1201 may include a fabric loop sewn or otherwise formed in theback of midsection 1203, and shopping cart liner 800 may include a tiesewn or otherwise formed near the bottom and back of the seating area ofshopping cart liner 800. Such a tie could be made of a fabric or othermaterial similar to the material the shell of shopping cart liner 800 ismade of. The tie could be threaded through the loop and tied to holdpillow 1201 in place, and can easily be undone to allow pillow 1201 tobe removed. The positions of the loop and tie could also be reversed,with the loop being part of shopping cart liner 800 and the tie beingpart of pillow 1201. Other kinds of connections are also possible. Forexample, a loop, tab, or other feature including the “hook” portion of ahook and loop fastener may be fixed to either pillow 1201 or shoppingcart liner 800, and a feature including the “loop” portion of thefastener fixed to the other, so that pillow 1201 could be attached toshopping cart liner 800 by engaging the hook portion and the loopportion.

In some embodiments, shopping cart liner 800 may be used or provided incombination or conjunction with other accessories useful to a user ofshopping cart liner 800. For example, a shopper who is caring for achild seated in shopping cart liner 800 may wish to carry items toattach to shopping cart liner 800, as well as other items such asdiapers, clothing for the child, or other items useful during a trip toa store. Accordingly, shopping cart liner 800 could be paired with atote bag or other accessory. A shoulder bag or other tote mayconveniently be made of materials similar to body 1001 of shopping cartliner 800, and may form a matching companion piece to shopping cartliner 800. Such a bag may also provide a convenient way to carry pillow1201.

FIGS. 13-15 illustrate additional details of how a track may be attachedto a piece of child care equipment, for example shopping cart liner 800.

FIG. 13A shows one way of attaching a track at a seam in a piece ofchild care equipment having a shell with two layers 1301 a and 1301 b.In this view, a rod or welt 1302 is shown in cross section, and servesas a track. For example, welt 1302 may be made of extruded, foam,plastic, or rubber. Rod or welt 1302 is wrapped in a sleeve 1303, shownin dashed lines. As is described above, sleeve 1303 may be made of amaterial having good durability and strength, for example nylon oranother suitable material. Preferably, sleeve 1303 is sewn alongstitching line 1304 to snugly capture rod or welt 1302 within sleeve1303, leaving two layers of sleeve 1303 protruding to form a tab 1305.

In this example, the shell is made in two layers 1301 a and 1301 b, witha padding or fill material 1306 between them. During construction, theedges of layers 1301 a and 1301 b may be generally aligned with the edgeof tab 1305, and the four thicknesses of materials (layers 1301 a and1301 b, and two thicknesses of sleeve 1303) sewn together alongstitching line 1307. It may be convenient to make the attachment ofsleeve 1303 to the shell with the shell “inside out”. Once the shell isnearly complete, it may be turned “outside out” and filled with paddingor fill material 1306. In this way, any edges of layers 1301 a and 1301b and sleeve 1303 that might be subject to fraying are inside thefinished product. A clip 350 or other clip according to embodiments ofthe invention may be engaged with rod or welt 1302, and the ends ofsleeve 1303 addressed to capture rod 1302 longitudinally. Alternatively,rather than sewing sleeve 1303 and layers 1301 a and 1301 b together ina single operation, rod or welt 1302 wrapped in sleeve 1303 may be sewnto either layer 1301 a or 1301 b in one operation, and then to the otherlayer in a later operation, so that there may be three stitching linesat a particular seam.

Rod or welt 1302 is preferably spaced from the body of the child careequipment by a distance D that is sufficient to enable clip 350 to slidefreely without catching on layer 1301 a or layer 1301 b. For example,spacing D may be about 1/16 inch to about ¼ inch, or more preferablyabout ⅛ inch to about 3/16 inch.

FIGS. 13B and 13C show another way of attaching a track to a piece ofchild care equipment, in accordance with other embodiments of theinvention. The technique of FIGS. 13B and 13C may be especially usefulfor construction of items that are generally flat but include padding,for example play pads, liners for shopping carts or strollers, or othersimilar items.

In FIG. 13B, a rod or welt 1302 has been previously wrapped in sleeve1303 and sleeve 1303 sewn along stitching line 1304 to capture rod orwelt 1302. Shell layers 1301 a and 1301 b are then stacked together withtab 1305 of sleeve 1303. In addition, a layer of sheet batting or otherpadding 1308 is also stacked together with tab 1305 and shell layers1301 a and 1301 b. In this configuration, the sides of layers 1301 a and1301 b that will form the outside of the product are facing each other.The combined shell layers 1301 a and 1301 b, tab 1305 of sleeve 1303,and padding 1308 are stitched together along stitching line 1309, whichmay extend along a portion or nearly all of the perimeter of theproduct. The stitching operation is preferably done with the product“inside out”, and a small portion of the perimeter of the product isleft unsewn, to allow for turning the product “outside out”.

FIG. 13C shows the arrangement of layers once the product is turned“outside out” and a clip 350 is attached. The small previously unsewnportion of the product perimeter may then be finished with outsidestitching or other finishing. A clip such as clip 350 is assembled ontothe track at any suitable stage of the process, but preferably beforethe ends of the track are fully finished.

FIG. 14 shows one way of attaching a track at an edge of a piece ofchild care equipment having a single layer of material 1401. In thisview, a rod or welt 1402 is shown in cross section, and serves as atrack. Rod or welt 1402 is wrapped in a sleeve 1403, shown in dashedlines. Preferably, sleeve 1403 is sewn along stitching line 1404 tosnugly capture rod or welt 1402 within sleeve 1403, leaving two layersof sleeve 1403 protruding to form a tab 1405. Each of the two layers oftab 1405 may then be folded under, and the single layer of material 1401inserted between them, and the five resulting layers of material sewntogether along stitching line 1406. In this way, any edges of material1401 or sleeve 1403 that might be subject to fraying are captured andhidden within tab 1405, between stitching lines 1404 and 1406.Alternatively, sleeve 1403 could be made of a self-edged material, andmaterial 1401 simply sewn between the two thicknesses of tab 1405,leaving the edges of sleeve 1403 exposed. A clip 301 or other clipaccording to embodiments of the invention may be engaged with rod orwelt 1402, and the ends of sleeve 1403 addressed to capture rod or welt1402 longitudinally. It will be recognized that this technique couldalso be used to attach a track at an edge of a piece of child careequipment having multiple layers capable of being captured within tab1405.

FIG. 15 shows another way of attaching a track to a piece of child careequipment having a shell with two layers 1501 a and 1501 b. In thisview, a welt 1502 is shown in cross section, and serves as the track.Welt 1502 is extruded, for example of foam, plastic, or rubber, toinclude an integrally formed flange 1503. Flange 1503 may be used toattach welt 1502 to layers 1501 a and 1501 b by sewing flange 1503 intothe seam between layers 1501 a and 1501 b. The sewing may be donesimultaneously, such as along stitching line 1504 capturing layers 1501a and 1501 b and flange 1503 in a single pass, or flange 1503 may besewn to the layers one at a time. Flange 1503 enables welt 1502 to beattached without being wrapped in a sleeve. The main portion of welt1502 (to which flange 1503 is connected), could be hollow, for exampleforming a tube with an opening along its length, or may be fully formedof the welt material, without any hollow portion. It will be recognizedthat welt 1502 having flange 1503 could also be attached to a singlelayer shell, or to a multiple-layer shell with both layers on the sameside of flange 1503. Many other configurations are possible. Welt 1502having a flange 1503 may replace a sleeve-wrapped welt or rod in anysuitable application, for example the applications shown in any of theFigures.

FIGS. 16A and 16B show a way of capturing the ends of a piece of welt ina seam between two fabric or other flexible layers 1601 a and 1601 b.FIG. 16A shows the assembly from the finished side of the seam, such asthe outside of a product, and FIG. 16B shows the assembly from theunfinished side of the seam, such as would be found on the inside of aproduct. Layers 1601 a and 1601 b are joined along seam 1602. For muchof the seam visible in FIGS. 16A and 16B, a track 1603 is sewn into seam1602, for example by wrapping a piece of welt in a fabric sleeve 1607and sewing the sleeve into seam 1602 as described above. At a pointwhere it is desired that track 1603 ends, track 1603 is turned inward,so that end 1604 of track 1603 will reside inside the finished product.Stitching 1605 is simply continued across track 1603 to capture track1603 securely in seam 1602. The point at which track 1603 is turnedinward also provides a stop that prevents clip such as clip 350 fromsliding past that point or from coming off of track 1603. If desired,multiple stitching passes 1606 may be made over track 1603 to lendstrength to the connection.
